  • Arrangement for an electric switching device
    Patent number: 10340107
    Abstract: An arrangement for an electric switching device is disclosed. The arrangement for an electric switching device comprises a switching unit having a first switching position and a second switching position, a restoring element exerting a restoring force on the switching unit in the second switching position, and a return spring fastened to the switching unit and exerting a counterforce on the switching unit. The restoring force is directed toward the first switching position, while the counterforce acts opposite to the restoring force.
    Type: Grant

  • Method and system of determining well performance
    Patent number: 6836731
    Abstract: A well optimization index WOI is an indicator for tracking trends and monitoring overall well performance. The WOI is a weighted average of two numbers reflecting operation execution performance (i.e., the Well Operation Time Ratio (WCTR)) and production result performance (i.e., the Productivity Index Ratio (PIR)). The WOI is calculated by a spreadsheet program used in a data-processing system. The spreadsheet program automatically generates the WOI for the well according to the expression: WOI = PI R ⁢ N + WCT R N + 1 ; wherein N is a weighting constant which represents a recovery of cost, that is estimated based on historical data.
